TheY body of the Vvhiclo (not shown is:

secured on the wooden sills B b v vertical ffl bolts F passing through the sills. These bolts extend through the wooden sills only and not through the upper flanges of the side beams. Therefore, the beams are not weakened by bolt holes in their Lipper flanges or compression members.' The attachment of the body is much more rigid when secured in this manner than when bolted to the upper flanges of the beams, as the latter are relatively* thin and liable to be bent or twisted by the strains due to the sidcwise swayingor wrenching of the body. Since holes do not have to be provided in the side beams or members of the metal frame for the body securiilp,r bolts, the position of the bolts is not restricted by reason ol' the construction of the frame or the parts mounted thereon, and the bolts can be located 'at thc moet convenient or suitable points or secon ing the body to the frame. the bolts being located differently in securing bodies of dit ferent constructions, if this is found to be necessary. y

I claim as my invention:

1. The combination with a vehicle frame having metal sid.: supporting members with laterally projecting upper flanges, of means for securing a body, platform or the like on said frame comprising attaching sills which extend lengthwise of and are supported on the upper flanges of said frame members,

securing devices for Said sills which are rigidly secured to said sills and are rigidly secured to said frame members below the nppcr flanges thereof, and fastening devices sills only, said bodv being complete independently of said sills.

Q. The combination with a vehicle frame having metal beam side members provided with vertical webs and upper laterally projecting: Hirnges, of meansfor securing abode",

. platform or the like on said frame comprising attaching sills for the vehicle body extondinor lengthwise of and supported on said hanged frame members, and securing brackets for said sills which are secured to tbc vertical webs of said frame members below the flanges thereof and have portions which embrace and are bolted to said sills and portions which embrace said flanged frame A,members for rigidly securing said sills iiulepcndently to said frame members, said sills haring provision for rigidly securing: the body thereon.
